BACKGROUND

1. Technical Field

The present disclosure relates to packing boxes or shipping boxes.

2. Description of Related Art

Most packing boxes for packing electronic products are provided with shock absorbing material to prevent the electronic products from being damaged. Such shock absorbing materials secure an electronic device in a packing box with a fastening mechanism and fill the packing box to surround the electronic device. The shock absorbing material is complicated and costly.

Therefore, there is room for improvement within the art.

FIG. 3 is one embodiment of a perspective view of a packing box 9 formed from the cardboard material 88 of FIG. 1. The rear side board 120, the left side board 130, the front side board 110, the right side board 140, and the fixed board 230 are folded along the folding lines 11, 12, 13, and 14 to be as four side boards of the packing box 9. The four side boards perpendicularly connect with each other to form a body 99 of the packing box 9. The fixed board 230 is fixed on the internal side of the rear side board 120. The first buffer board 210 is folded toward the left side board 130 along the main folding line 26 to have the first buffer board 210 substantially perpendicular to the left side board 130. The first buffer board 210 is further folded upward along the fourth folding line 212 to have a portion of the first buffer board 210 between the fourth folding line 212 and the first edge 216 substantially parallel to the left side board 130.

One of the left buffer portions 818 connects with the front buffer portion 812 and is surrounded by the folding lines 60 and 61, the slit 2168, the fourth opening 2164, and the sixth opening 2166. Another one of the left buffer portions 818 connects with the rear buffer portion 814 and is surrounded by folding lines 56, 57, the third opening 2163, the first opening 2161, and the fifth opening 2165. The second buffer board 190 is folded toward the left side board 130 along the first folding line 192, the second folding line 194, and the third folding line 196 in sequence to form a second buffer part 820. The second buffer part 820 connects with the left side board 130.

The third buffer board 220 is folded to form a third buffer part 830 with the same way as folding the first buffer board 210 to form the first buffer part 810. The third buffer part 830 is fixed on the right side board 140. The fourth buffer board 200 is folded to form a fourth buffer part 840 with the same way as folding the second buffer board 190 to form the second buffer part 820. The fourth buffer part 840 connects with the right side board 140. The front bottom board 150 is folded along the main folding line 21 and the rear bottom board 160 is folded along the main folding line 23 to jointly form a bottom board of the packing box 9. The seam between the front bottom board 150 and the rear bottom board 160 may be sealed with adhesive tape.

FIG. 5 is another embodiment of a perspective view of the packing box 9, formed from the cardboard material 88 of FIG. 1. Referring to FIGS. 1, 4 and 5, the front insertion board 240 is folded along the two sixth folding lines 242 to form a fifth buffer part 850. Two ends of the fifth buffer part 850 are configured to individually lock on the first buffer part 810 and the third buffer part 830. The fifth buffer part 850 includes a buffer portion 852, a first fixed portion 854, a second fixed portion 856, and an insertion portion 858. The buffer portion 852 is located between the first fixed portion 854 and the second fixed portion 856, and is formed by folding the middle portions 244 and the buffer tabs 2462 along the two sixth folding lines 242. The first fixed portion 854 is formed by overlapping the pair of first insertion tabs 2464. Two ends of the first fixed portion 854 are located in the first opening 2161 of the third buffer part 830 and the rectangular opening 202 through the slits 2469. The second fixed portion 856 is formed by overlapping the pair of the second insertion tabs 2466. Two ends of the second fixed portion 856 are located in the second opening 2162 and the rectangular opening 198 through the slits 2469. The insertion portion 858 is formed by overlapping the two insertion tabs 2468 and located between the second fixed portion 856 and the left side board 130 through the slit 2168.

The rear insertion board 250 is folded to form a sixth buffer part 860 the same way as folding the front insertion board 240 to form the fifth buffer part 850. Two ends of the sixth buffer part 860 are located on the first buffer part 810 and the third buffer part 830. The structure of the sixth buffer part 860 is roughly the same as the fifth buffer part 850. Difference between the sixth buffer part 860 and the fifth buffer part 850 are that the sixth buffer part 860 has no insertion portion 858 and the second fixed portion 856 of the sixth buffer part 860 is shaped like a hook. The second fixed portion 856 of the sixth buffer part 860 is configured to hook on the third buffer part 830.

When packing an object with the packing box 9, the object is located between the first buffer part 810, the third buffer part 830, the fifth buffer part 850, and the sixth buffer part 860. The second buffer part 820 and the fourth buffer part 840 are covered on a left end and a right end of the object. The first buffer part 810 and the second buffer part 820 are opposite and located on a bottom and a top of the left end of the object. The third buffer part 830 and the fourth buffer part 840 are opposite and located on a bottom and a top of the right end of the object. The front top board 170 is folded along the main folding line 22 and the rear top board 180 is folded along the main folding line 24 to jointly form a top board of the packing box 9. The seam between the front top board 170 and the rear top board 180 may be sealed with adhesive tape.

The body 99, the first buffer part 810, the third buffer part 830, the second buffer part 820, and the fourth buffer part 840 are integrated. The object may be located between the first buffer part 810, the third buffer part 830, the second buffer part 820, and the fourth buffer part 840 without filling shock absorption material in the packing box 9 while packing.
